DX AIR CURTAIN SensAir
Biddle and Daikin Complete climate system Since 2006 Biddle and Daikin have joined forces to provide a complete climate system for shops and public buildings. By combining Biddle air curtains with the highle efficient Daikin heat pump systems, a lot of energy is saved and comfort in the building is optimum. Maximum comfort Both visitors and personnel can enjoy maximum comfort during the whole year, under all weather conditions. This is the result of the efficient climate separation created by Biddle air curtains, while heat pump systems heat, cool or ventilate to provide a comfortable indoor climate. Integrated air conditioning solutions The advantage of combining air curtains with heat pumps and heat recovery is that climate separation, heating, cooling and ventilation are combined in one system. Considerable savings on energy costs can be made as compared with traditional systems; this means that the payback time is very short, generally about 1.5 years. The stable indoor climate due to efficient climate separation reduces heat loss through the doorway and also increases the efficiency of the Daikin systems. A Daikin heat pump is very efficient and saves up to 40% of energy costs as compared with a high-efficiency central heating boiler. A Biddle air curtain in combination with Daikin s heat pump systems is the ultimate energy-saving solution for cooling, heating, ventilation and climate separation and means that other energy generators, such as a central heating system, are not required. Daikin climate systems Biddle air curtains can be installed plug&play to various Daikin climate systems. Heat pump/heat recovery: for heating and/or cooling a building. The heat released from cooling systems (residual heat) is recycled for the Biddle air curtain. Conveni-pack: a unique total solution for refrigerated storage and air conditioning, where energy consumption is reduced to a minimum as up to 100% of the heat is recovered from cooling equipment and used to heat the area. This is without additional costs.
SensAir DX air curtains A new wave in climate separation SensAir air curtains are the ideal solution for retailers and other end-users to combat the issue of climate separation across their outlet or office building doorway. The importance of accessibility to attract customers in the retail sector is well-known, but with this free form of access through open door trading, cold draughts and high-energy bills are often the consequence. High comfort and energy efficient The SensAir technology has been improved to deliver greater comfort for all, whether it is in a supermarket, high street store or office building. The SensAir air curtain, does not act as a barrier in the place of a door, its prime role is to reduce the amount of warm air leaving the building and condition the incoming air to a comfortable temperature. BSRIA and Biddle research produced documented evidence proving that air curtains operate best with specific velocities and air volumes. The SensAir air curtain satisfies these needs by delivering the right air flow and temperature at the right time automatically, reducing energy loss. Furthermore it is the only commercially available air curtain of its kind that now offers a unique air damper system to improve efficiency, by controlling the outlet velocity. Intelligent auto-active control and monitoring The auto-active control is the next generation of controls. Knowing that manual control of air curtains often leads to the incorrect setting the inclusion of the automatic CHIPS (Corrective Heating & Impulse Prediction System) technology ensures the most appropriate setting at any moment in time. The i-sense in the discharge grille measures the indoor and outdoor temperatures active in the door opening resulting in accurate data. This auto-active control has been demonstrated to produce energy saving savings of up to 75% when compared with a manually controlled air curtain. Biddle has an extensive range of control options: the b-touch control panel, remote monitoring of comfort and energy performance and connecting to a BMS is easy through the standard integrated Modbus connection. Benefits Energy efficient and high comfort - improved accuracy of temperature data collection - correct settings are adjusted actively and automatically - comfortable inside climate and inviting appearance - low sound level Intelligent control and monitoring - self-regulating: auto-active control - remote monitoring: b-connect - Modbus: integrated as standard Installation & maintenance-friendly - easy to assemble and set up (b-touch) - ready-to-use, integrated control Complete customized solution - customer specific styling possible - suitable for various heat sources
SensAir and Daikin Energy-efficient climate concept Biddle and Daikin supply a complete plug & play climate concept. Within this energy-efficient climate concept two different versions are available: the SRV and SRQ models. Complete SRV air curtain climate system The climate system consisting of the SensAir air curtain, model SRV (1), Daikin VRV outdoor unit (2) and indoor units (3) supplies heating, cooling, ventilation and climate separation in one energy-efficient installation. By heating and cooling at the same time the heat extracted from the cooling systems can be extracted for the air curtain, thus resulting in considerable reduction in energy costs. This integrated climate system is energy efficient, has a quick payback time and provides a comfortable indoor climate. Standalone SRQ air curtain heat pump The SensAir air curtain, model SRQ (1), is available in combination with a Daikin ERQ heat pump (2). The heat pump provides the heating energy required for climate separation in the doorway. The heating and cooling in the building are controlled separately (3). Considerable energy savings are obtained by connecting the SensAir to a heat pump: up to 40% as compared with a high-efficiency boiler and even 73% as compared with an electric air curtain. This climate solution is sustainable, energy saving and creates a pleasant indoor climate. The SensAir is also available as a hybrid DX version Constant heating with hybrid SensAir The hybrid SensAir consists of a DX and an additional electric heating element. First maximum use is made of the available heat from the DX. If necessary, the electric element switches on automatically so that the required discharge temperature can be achieved continuously. In cold weather the electric element switches on automatically if the outdoor unit is not adequate to supply the capacity required. The electric element also supplies the heating required during the defrosting cycle. In this way climate separation is always guaranteed.
SensAir auto-active control Intelligent control and monitoring There are an extensive range of control options; touchscreen control (b-touch), remote operation and integration with a Building Management System (BMS). It is possible to monitor the energy performance and comfort levels remotely by means of the b- connect monitoring module. Connecting to a BMS is easy through a standard Modbus Protocol connection, whilst it is also possible to communicate via BACnet. All SensAir devices are fitted with Biddle's innovative auto-active control, the next generation of controls. Auto-active control Generally, installing an air curtainis typically set to operate at a mid-speed setting and rarely adjusted. This results in the air curtain continually operating at a single air volume, velocity and temperature. However, as internal and external conditions constantly vary this means the air curtain will only be operating at the optimum setting some of the time, and for the rest of the time will be on either too high or too low a setting. The automatic CHIPS (Corrective Heating & Impulse Prediction System) technology ensures the most appropriate setting at any moment in time. The i-sense in the discharge grille measures the indoor and outdoor temperatures active in the door opening resulting in accurate data. This process ensures that the SensAir is always functioning correctly and yields an ideal, energy-efficient indoor climate without interference of the user. b-touch control panel A revolutionary combination of technologies SensAir s auto-active control combines no fewer than four renowned Biddle technologies. The revolutionary patented i-sense infrared technology collects all temperature-related data in the doorway. CHIPS technology translates this information into the correct setting, whilst the adaptable discharge width (Controlled Air strength technology) and the patented rectifier create the perfect climate separation. Benefits Combination SensAir - Daikin - Sustainable climate solution - Integrated climate system possible - Extensive control options - Extremely low energy consumption - Low investment costs (no central heating needed) - Optimal comfort - Low CO -emission 2 You will find more information regarding SensAir s commercial advantages in a separate brochure.
SensAir selection Air curtain selection Selecting the right air curtain is crucial in order to ensure the SensAir works optimally. An air curtain performs properly when it completely shields the doorway and is strong enough to heat the cold air streaming in from outside to acomfortable temperature. 1. Installation height Selecting an air curtain is a simple process, achieved by taking installation height (floor to bottom of unit) and door width into account (see adjacent diagram and selection table). 2. Natural ventilation The volume and temperature of the incoming outside air are hard to measure because the climatic circumstances around the doorway are constantly changing. Structural issues also influence capacity requirements. The following guidelines generally apply when it comes to choosing your device: Favourable: indoor shopping centre, sheltered shops Normal: moderate direct wind attacks, no open doors facing each other, ground floor Unfavourable: on a corner or square, several floors, open staircases Selection table Proper installation In order to guarantee proper functioning, the distance between the air curtain and the door should be as small as possible, whilst the curtain itself should be at least as wide as the doorway. situation favourable normal unfavourable type door height (cm) S < 240 < 220 - M < 280 < 250 < 220 L < 330 < 300 < 280 XL < 400 < 350 < 320 Simulation tool Biddle has developed a simulation tool to help you select the right air curtain: VACP (Visual Air Curtain Performance). Biddle has specific advice for all doorway scenarios. For more information, please contact Biddle s sales department.

SensAir DX specifications Specifications Casing The casing is made of zinc plated sheet steel, and has an inspection panel in the bottom. The inlet grilles are made of anodised aluminium with fixed fins. The inlet module and the end panels as well as the casing are, as a standard, supplied in silver grey (RAL 9006) or traffic white (RAL 9016). The end panels of the white SensAir have a grey inlay. Other RAL casing colour finishes are available for an additional charge. Motor / Fan assembly The air curtain is equipped with two or more (depending on type) dual-inlet, vibration free suspended centrifugal fans. Each fan is driven by arotor motor on bearings, which are seal for life and no maintenance is required. The fan casing and the impeller are made of zinc coated plate steel. The motors, as standard, are fitted with thermal contacts. These thermal contacts break the circuit of the motor when the maximum permissible motor temperature is exceeded. Heating coil DX: made up of 3/8" copper tubes and aluminium fins. The fluid connection is 9.52 mm, and the gas connection is 16 mm (with 100, S/M-150 & 200, S-250), 19 mm (with M-250, L/XL-150) or 22 mm (with L-200 en 250). Hybrid: a combination of DX with an electrical stitched wire heating element. Connections To connect DX units to the mains supply, they come with a fixed cable (approx. 2 m long) with a moulded, earthed plug. The connection for Daikin units and the connector plate are fitted on the top of the unit. The mains cable for electrical heating must be connected within the unit. The top of the unit has a cable gland for feeding through the feeder cable. A 5-core cable (3 phases + earth + neutral) is required for proper connection.
SensAir DX explanation of technical data Explanation technical data Because of the auto-active control of the SensAir DX air curtain the outlet temperature varies at all speeds, depending on the situation. The maximum heating capacity of the DX air curtains is the same as the heating capacity in the highest fan speed. Selection Daikin outdoor unit To determine the correct Daikin outdoor unit for model SRV, you need to add together the capacity indexes of all the indoor units. Sound The sound data is based on the direct field, in a situation with an open door and a sound absorbing ceiling. The sound data for different situations can be determined by adding the adjacent values to the table values. Closed door Acoustical "hard" ceiling + 1 à 2 db(a) + 2 à 3 db(a) Deviating distances and several units next to each other can be calculated with the table below. Data from the 1 m unit, measured at a distance of 3 m, is the basic assumption. The factors apply to all types of air curtains.
